Hi - Yield Atrazine Weed Killer RTU is not labeled to be used on Zoysia turfgrass and to only be used on St. Augustine and Centipede lawns.
We would recommend Quali-Pro MSM Turf Herbicide to treat for spurweed in Zoysia after the new turfgrass has been mowed atleast twice or afte 30 days. Per the product label, apply 0.25 to 1.0 oz of MSM Turf Herbicide per acre for weed control. Some chlorosis or stunting of the turfgrass may occur following application.
Hi-Yield Atrazine Weed Killer RTS is only labeled for suppression of crabgrass therefore will not fully control it.
We would recommend spot treating the crabgrass with a non selective glyphosate product such as Roundup Quick Pro then reseed/resod any bare spots after 2 weeks..
Yes, Hi-Yield Atrazine Weed Killer RTS is slow acting post emergent and 4-6 weeks is accurate to see desired results
